I have issue with X557-AT adapters. It doesn't negotiate 10Gbe speed with a L2 switches. I've tested Cisco/Dell/Ubiquiti.
I check both case setting to auto and setting manually speed and duplex.
When driver is loaded if you bounce a port, it negotiate a link to 1Gbe link instead of 10Gbe.
I'm using 1.4.1 firmware.
Firmware version 0x800005ad.
Where I can get latest firmware and re flash adapter ?
The driver is latest driver for ESXi 6.7 Update 2. I cross check older driver / different version of ESXi. It same issue.
Thank you for contacting Intel Embedded Community.

We are waiting for your answer.
It Supermicro motherboard X10SDV-TLN4F
It has on board two 10Gbe adapter.
I believe it has some issue with auto-sensing 10Gbe link speed. There are number of reports
on internet, as far I understood Intel has a firmware that fix that issue.
Thanks for your reply.
